Adding your developer account as a Street Team member in your non-development account; you’ll need to make the request from the latter and then approve it from the former.

For each activity you wish to copy from your non-development account into your developer account, tag the developer account from that activity’s page; this copies the activity data into your developer account.

Optional: When you’re done tagging and copying data, you can remove the tags while in your developer account, then remove your non-development account from your developer account Street Team, to sever the linkages but keep the copied data.

One more option: You can export an existing user’s data (click here for details) then parse that data and write it back into your own developer account via the Health Graph API. In fact, doing so is very instructive as it requires you to explore several different aspects of the Health Graph platform.

The above options should give you plenty of ways to get test data together for your application. I hope this helps and happy health hacking!
